It is C) because that truck has more mass
0.022 has 2 digits because you would count from the left starting with the first nonzero number
By definition, we have to:
Calcium Bromide is an inorganic salt formed by granular white crystals that responds to the formula CaBr2.
Calcium bromide has no odor, is colorless and has a bitter taste.
It is obtained by adding Hydrobromic Acid to Calcium Oxide, Calcium Carbonate or Calcium Hydroxide.
The substance that results is then subjected to a crystallization process, which involves evaporating the water.
From here, you get then:
CaBr2.
Answer:
CaBr2 = Calcium bromide.
The speed of a wave, c, is given by the length of the wave, λ, times the frequency (times per second a cycle passes). Since frequency has units of inverse seconds, the units will then be m/s as we expect.
Any moving object in space will travel in a straight line at the same speed forever, planets included. The planets would be moving in straight lines, but the sun's gravity pulls them toward it. The force of gravity causes the moving planets to travel in roughly circular orbits around the sun.
